Dehydration of terpin hydrate in the presence of various ion-exchange resins was written by Isagulyants, V. I.;Fedorova, R. I.. And the article was included in Tr., Mosk. Inst. Neftekhim. iGaz. Prom. in 1964.Formula: C10H22O3 This article mentions the following:
During dehydration of terpin hydrate in the presence of cation exchange KU-2 (2%) as catalyst, dl-α-terpineol (I) was obtained in 62% yield. Cineole was not found. In the presence of cation exchanger KU-1 under the same conditions the yield of I was 37%. Best results were obtained in the presence of a sulfocarbon (10%) as catalyst. After 4 times the yield of I was 68% of the theoretical. In all cases I was distilled with water vapors as soon as it was formed to avoid its further possible dehydration to hydrocarbons. In the experiment, the researchers used many compounds, for example, rel-(1s,4s)-4-(2-Hydroxypropan-2-yl)-1-methylcyclohexanol hydrate (cas: 2451-01-6Formula: C10H22O3).
rel-(1s,4s)-4-(2-Hydroxypropan-2-yl)-1-methylcyclohexanol hydrate (cas: 2451-01-6) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Formula: C10H22O3
